Young hard-throwing right-handers Trevor Rosenthal and Carlos Martinez, whose contract was purchased Friday from Double-A Springfield, stymied the Brewers in the first two games of the series. Both were throwing in the mid to high-90s at Miller Park.
"And that's why I say, no matter what their [bullpen] numbers are, it's uncomfortable when you're facing a guy throwing that hard," Roenicke said.
Cardinals manager Mike Matheny said Martinez and Seth Maness, who each pitched a scoreless inning in their Major League debuts Friday night, give him more flexibility out of the bullpen.
"It definitely gives us more options," Matheny said. "They both have a real good dispositions to them. Carlos came off the field and wanted to start hugging people [Friday night]. You could tell how excited he really was. He came out of Double-A so you can understand why."
Both Martinez and Maness were starters in the Minors, but were available to pitch on consecutive days against the Brewers.
"It's kind of a new experience for them, but they've been built up and are well-rested," he said.
